FLASH-IGNITER AND SIMMERER.

v Specification of Letters Patent.

Patented June 41, 1918.

Application flied August 3, 1917. Serial No. 184,258.

To all whom it may concern.

Be it'known that we, J onus F. Rum and FRANK A. GAUGER, both citizens ofthe United States, and residen s of Milwaukee, inthe county of Milwaukeeand State of Wisconsin, have invented certain new and usefulImproyements in Flash-Igniters and Simmerers; and we do hereby declarethat the following is a full, clear, and exact description thereof.

The present invention relates to burners adapted to use gaseous fuel,and its objects are, among others, to provide simple and effective meansfor controlling the flow of the fuel to a burner for lightingthe-burners simultaneously or successively from a common pilot light,and for producing and controlling a low simmering flame, and forprotecting the parts against impairment b y w the accumulation ofcarbon; and to provide means for guarding against various undesirableresults which sometimes follow from the ;careless use of such burners.

The invention comprises a valve controlling a plurality of Ways and aburner which may act as a lighter for a plurality of other provision ofa triple control valve for operating the simmerer, flash igniter andpilot and comprises a simple and compact structure having a singlespring means therein for retaining the valve head in the valve casingand the auxiliary valve normally closed.

With the above and other objects in'view, which will appear as thedescription proceeds, our invention resides in the novel construction,combination and arrangement of parts substantially as hereinafterdescribed and particularly defined by the appended claims, it beingunderstood that such changes in the precise embodiment thereof may bemade as come within the scope of the claims.

In the accompanying drawings we have illustrated one complete example ofthe physical embodiment of our invention constructed according to thebest mode we have so far devised for the practical application of theprinciples thereof, in which:

Figure 1 is a side view thereof with parts broken away and in section tomore clearly define structural details.

Fig. 2 is a sectional view through the burner member on the line 2-2 ofFig. 1.

Fig. 3 is a plan view of the underneath side of the partition betweenthe burner head and simmerer.

Fig. 4 is a sectional view taken longitudinally through the valve.

Fig. 5 is a sectional view, taken on the line 55 of Fig. 4:, and

Fig. 6 is a sectional view taken on the line 66 of Fig. 4. v

Referring now more particularly to the accompanylng drawings, the triplecontrol valve structure includes a main casing 5 having its boretaperingly' reduced toward its lower end in the usual manner of gasstove valves for the reception of a similarly tapered valve head 6 tothe upper end of which is secured a handle 7. Extended from one side ofthe casing is a nipple 8 whereby the casing is secured to the usual mainsupply pipe (not shown) at the front of the stove and extending from theopposite side of the casing is a boss 10 for the securement of theburner supply pipes.

This valve head controls the flow of gas to the simmering burner, andalso controls the-flow of gas to the flash igniter which further servesthe purpose of a pilot, and the means for controlling the flow of gas tothe simmerer comprises openings in the valve head 6 adapted to registerwith the supply opening 11 in the nipple 8 and an opening 11 in the boss10 from which leads a supply pipe 12 to the simmerer to be laterdescribed. The upper. end of the valve head 6 is hollow as at 13 and hasextending therethrough a central bore 14 in which is slidably mountedthe shank 15 of the controlling valve 15 for the flash igniter.

Disposed beneath'the valve head 6 are two compartments 16 and 17 dividedby a wallor partition 18 which is centrally and taperingly apertured toprovide the seat for valve 15 and the upper compartment 16 communicatesby Way of passage 16 with the gas supply pipe 19 for the flash igniterwhich has its end screwed into the boss 10, said supply pipe 19surrounding the pipe 12, and the other compartment 17 communicating bymeans of passage 17 with the gas inlet 11. A small opening 20 beingnormally opened leads from the passage 17 to the compartment 16 in orderto provide a small but steady flow of gas at all times to the flash 7larged bore 13 of the valve head and surrounding said shank in said boreis an expansile spring 22 urging upwardly against the under side of thebutton 21. The functions of this spring 22 are various and 'consist inretaining the packing 23 firm against the shank 15 to make a gas tightjoint, to normally retain the tapered valve head 15' in its seat and tofurther retain the main valve head 6in the tapered bore of the maincasing.

Taking up now the construction of the flash igniter and simmerer, thesame comprising essentially a shell or inverted cup member 25 which isusually punched from 'a Y sheet of light metal and has in its top closedportion a series of apertures 26 and separating this top portion into achamber or compartment 27 is a partition 28 having its pe ripheral edgesbent laterally to form a flange for engaging the inner peripheral wallof the member 25 and has therein near one edge an aperture 29 havinglateral flanges therearound for engagement with a connecting nipple 30whichengages a spray and mixing head 31 having spray opening 32 and airopenings 32. H v

This mixing head 31 is carried by a casting 33 and communicates with thesupply pipe 12 through which the-supply of gas 1s 0011-.

trolled by means of the valve head 6. The casting 33 is supported bymeans of the supply pipe 19 which communicates with a flash igniter 34by means of passage 35 and said flash igniter has in its upper closedend a series of openings 36 each opposite an aperture 37 in. the shell25 so that when a sudv den supply of gas is sent through pipe 19, a..

stream of flame will-shoot from each opening 36 through apertures 37 tothe gas stove burners (not shown) thereadjacent.

In order to prevent soot or carbon from forming in the chamber about thepilot and flash igniter 34 a series of apertures 38 are formed about theshell 25 to insure a circulation therethroug'h of air. The simmerer isignited by the flames from the flashigniter apertures 37. This isreadily possible inasmuch as upon the openingor closing of the valvewhich feeds gas to the igniter burner 34 the flames will tendfto, creepor lick up the sides of the hood25 and reach the gas which is'issuingfrom thela-pertures 26.

Thus from the foregoing description taken in connection with theacompanying drawings it will'be obvious that a small pilot light isalways burning at the flash igniter 34 and when the button 21 isdepressed a sudden flow of gas will pass through pipe 19 and cause aflame jet to project from each opening36 of the flash igniter and playon its adjacent burner, and that when it 1s desired to ignite thesimmerer, vthe openings in the valve head 6 are alined with the openings11 and 11' and at the same time the button 21 is depressed ashereinbefore described.

The present arrangement occupies but little more space than either thesimmering burner structure or the flash igniter structure-alone andconsequently conduces materially toward a desired compactness of stovestructure, in addition to'the provision of a 4 central p'ositionin ofboth the simmering and flash igniter urners and a triple control valvefor the burners.

We claim: 1 I 1. In a structure of the class described, a

control valve including a bored valve casling, said casing having a"single inlet and two outlets, saidin-let and outlets communicating withthe bore of said casing, a valve-head in said bore for controlling thepassage of fluid from the inlet through one of said outlets, a passageleading from, said inlet, and means carried by said valve head a andindependent thereof for connecting said passage and the other of saidoutlets;

2. In a structure of theiclass described, a triple control valveincluding a ,valve casing having a single inlet and two outlets,-saidcasing having a central bore, a valve-head in the bore, a passage inthe'valve head adapted to. register withand connect said inlet with oneof said outlets, an auxiliary valve mounted in said valve head andadapted to connect the saidinlet with the-other of said outlets, andmeans for normallyclosing said auxiliary valve.

3. In a structure of the class descrlbed, a

triplecontrol Valve including'a. valve casiliary valve for normallyclosing said aperburner 34 which project through the large ture and forretaining said valve head in the casing.

engaging a central aperture between said compartments, and spring meansfor normally seating said auxiliary valve in said aperture and retainingthe valve head in the casing.

" 5. A combined simmerer and flash igniter comprisin a hood memberadapted to be stamped from a single sheet of material, said hood memberhaving openings in its top wall to provide a simmering burner. and aseries of openings in the side wall, a partition near the closed end ofsaid hood member below said first mentioned openings therein, saidpartition having an opening, a lateral flange formed on the peripheraledge of said partition and engaging the inner wall of the hood member, aflange surrounding said opening in saidpartition, a nipple engaging thelast mentioned flange, a spray nozzle projecting into said nipple andhav ing an air passage surrounding the same, a flash igniter' disposedin the hood mem': ber beneath the partition and having a series of -jetopenings therein alining with the series of openings in the side wall ofthe hood'member, a supply pipe for the flash igniter, a supply pipe forsaid spray nozzle, and a valve for controlling both of said supplypipes.

In testimony that we claim the foregoing We have hereunto set ourhandsat Milwaukee, inthe county of Milwaukee and State of Wisconsin.
